Abstract

We report an all-optical modulator with 75 photons at 2 GHz, using a tapered nanofiber embedded in an alkali vapor. The switching energy is 19 atto-Joules, a record low value for modulation at this speed.

All-optical modulation of four-wave mixing in an Rb-filled photonic bandgap fiber

Vivek Venkataraman, Pablo Londero, Amar R. Bhagwat +2 more

We demonstrate efficient all-optical modulation using Rb vapor confined to a hollow-core photonic bandgap fiber. The intensity of a signal field participating in the four-wave-mixing process is modulated using a weak switching field. We observe 3 dB of attenuation in the signal field with only 3600 photons of switching energy, corresponding to 23 photons per atomic cross section lambda(2)/(2pi). Modulation bandwidths as high as 300 MHz are observed.

We show 20% all-optical modulation with less than 2 nW total power via non-degenerate two-photon absorption in Rb vapor confined to a photonic bandgap fiber. This corresponds to about 15 photons of switching energy.
